Get car wash now car won’t drive over 20pmh

Hello, the check engine light is an indicator that diagnostic trouble codes have been set in the engine's processor that are likely related to the performance problems you are now experiencing. Although I cannot be sure, sometimes when you get water into the engine compartment somehow, it can cause engine misfires due to spark "leak" arcing from ignition components that are exposed to moisture. I would be looking at this second -- first would be detecting with a diagnostic tool what trouble codes are present so you can focus the troubleshooting on the areas that need attention.
